April 19, 2011 11:00 ET Publishes Power Architecture® 32-bit Application Binary Interface Supplement

PISCATAWAY, NJ--(Marketwire - Apr 19, 2011) -, the organization that promotes and develops standards for Power Architecture® technology, announced the availability of the Power Architecture® 32-bit Application Binary Interface Supplement that is current with Power ISA 2.05 (Power Architecture® 32-bit ABI Supplement 1.0). The supplement, collaboratively prepared by Code Sourcery (now part of Mentor Graphics), Eager Consulting, Freescale Semiconductor, Green Hills Software, IBM, and Wind River, provides detailed documentation on the current state of the 32-bit Power Architecture processor-specific ELF ABI as implemented for the Linux Operating System and embedded environments. The new document, which includes every unique update generated by interested parties of the ABI, was published under the GNU Free Document License (Version 1.3).

The original 32-bit PowerPC ELF ABI document, "System V Application Binary Interface: PowerPC Processor Supplement," which was published in September 1995, was created cooperatively by IBM and SunSoft using UNIX System Laboratories, Inc. copyrighted material with permission. Since then, the advancement of Power Architecture hardware, improvements in security, and the maturation of the generic ELF ABI specification, necessitated numerous changes to the specification.

The information in the new ABI document was largely derived from the 64-bit Power ELF ABI, E500 ABI, EABI, TLS ABI, and Secure-PLT ABI. By publishing the supplement under the GNU Free Document License, future loss of revision authority is prevented.
